How to solve the capsule filling powder too sticky When the capsule filling machine is working, if the working powder is too viscous, it can be generally improved from the following points: 1. If the hygroscopicity of the powder causes the powder to be too sticky, the hygroscopicity should be reduced as far as possible, and the effective extraction process should be carried out to retain the part of the powder containing more starch, or some auxiliary materials should be added to reduce the hygroscopicity. 2. Keep the powder as dry as possible, less water is better. 3. Reduce the humidity and temperature in the workshop. 4.The packing of the powder must be close and effective against dampness and moisture. 5. Keep the powder as fine and even as possible. 6. The filling rod of the machine should be checked and replaced in time if there is any wear. 7. Add auxiliary materials to increase the fluidity and lubricity of the powder.

Peristaltic pump of liquid bubble wrap machine A peristaltic pump is like a hose with liquid between your fingers. When you slide your finger forward, the fluid in the tube moves forward. Peristaltic pump works in the same way as using a roller instead of a finger. Fluid is pumped through alternate extrusion and release of the pump delivery pipe. Just like using two fingers to tighten the hose, when the fingers move, negative pressure is created in the tube and the liquid flows. Peristaltic pump is a section of pump pipe between two rollers, forming a buffer shape of the fluid. The volume of the gasket depends on the pump's inside diameter and rotor geometry. The flow depends on the product of three parameters, namely the speed of the pump head and the size of the gasket, and the number of gaskets produced during each rotation of the rotor. The pad's size is usually constant (unless it pumps a particularly viscous fluid). Compared with the pump with the same rotor diameter, th

Factors influencing the accuracy of capsule filling machine The operator did not add powder as required in the manual before starting. Before operation, the powder is respectively loaded into the hopper and sent to the measuring room through the feeder. The measuring chamber should contain more than half of the powder before filling. The operator did not replenish the materials in time during the operation, which directly affected the filling state of the drugs in the measurement model, leading to the difference in the quantity. The fluidity and viscosity of drugs are the main factors affecting the measurement accuracy. Due to the lack of fluidity of the drug, the powder viscosity is high, the filling volume is difficult to control, and the connection between the measuring plate and the copper ring may also occur. The drug is not uniform, the particle size difference is big, the particle is thin and thick, fluidity is poor. In order to solve the problem of drug fluidity, it is nece

The performance of the tablet press The granule powder can be pressed out according to the requirements of various tablet shapes.

Adjust the handle to the highest position and observe whether the die on the bottom punch is flush with the middle die. If not flush, adjust a butterfly screw. It has the function of starting and stopping point and speed reg

Blister forming problem Industry experts point out that the principle of forming bubble cover is that PVC hard sheet is heated by molding fuel and compressed air or vacuum to form the required shape and size of bubble shell. Therefore, when there are problems in bubble shell, the following aspects need to be solved: PVC diaphragm material qualified or not; The temperature of the heating device is too high or too low; Whether the heating device surface is connected with PVC; Whether the mold is suitable, whether the mold hole is smooth, whether the porosity is unobvious; Whether the mold cooling system is normal and effective; Whether the vacuum degree and exhaust velocity of the negative pressure forming of the drum can reach the normal value and whether there is abnormal leakage of the pipeline; Clean and dry the positive pressure plate with compressed air, check whether the pressure and flow rate are normal, check whether the pipeline leakage is abnormal; Is the positive die parall

The difference between a single stamping machine and a rotary stamping machine A single stamping machine works by pressing powder particles into pieces. Single stamping machine excellent performance, adaptability, easy to use, easy to maintain, manual and electric two ways to work. Single stamping machine only one stamping die, easy to use, by the pharmaceutical industry and other welcome. The tablets are of average thickness and do not require reprocessing. Rotating machinery concrete working method of the compressor is a rotary tablet, basic guide manufacturers need to periodically check the machine and spare parts, bearings, turbine pressure, crankshaft, and so on up and down, found that the problem must be solved, otherwise it will damage the machine running, after each use, need to clean the residual material, if must use for a long time to die down and clean. The maintenance of the die should be put in a rusty box. If no iron box is available, special iron boxes should be c

The composition and function of the capsule The capsule is mainly made up of starch and contains a drug that can stimulate the stomach. Because the stomach does not absorb starch, the capsules deliver the drug directly to the small intestine, avoiding stomach irritation. The hollow eggshell made of food-grade medical gelatin is treated with excipients and used for packaging solid powder and particles. The capsule shell has good bioavailability, high dissolution rate, reliability and safety. Capsules are mainly used in pharmaceuticals and the pharmaceutical industry. Medical hollow capsules are mainly used in bulk, health products, medicines and other solid medicines. First, the stainless steel mold on the formation of a rubber film. The gelatin film is then dried and hardened to form a capsule, which is then removed from the mold. There are usually two sizes of mold, one for making the capsule body and one for making the capsule cover. But some capsules made with industrial

Temperature control of blister packing machine According to our understanding and analysis of blister packaging machine, the control of three places is more critical. First is the temperature control of the heating plate; Secondly, good position control must be realized in order to realize punching and tearing process. Finally, the forming bubble shell and the hot seal plate are controlled to make them consistent. Therefore, the main control of the mechanism consists of three parts: temperature control module, counting and position detection control module, and heat sealing module. The temperature control module is mainly composed of temperature sensor and thermostat. Used for preforming and heat sealing device. The device is composed of upper and lower heating plates, forming molds and heat sealing molds. Combined with pneumatic equipment, the main process of packaging machine - foaming molding and heat sealing. According to the thermoplastic principle, bubble formation requires

The tablet problem of the tablet press It is very common for pills to have black spots and other colored spots. According to the specific situation, the choice of pills is certain. So how can we find out the reason? If it's a black spot, it could be a carbonized raw material, or it could be a loose handle on the ring. If the color is different, then it is necessary to check the different parts of the tablet press, rule out different possibilities. Missing edge is also a common problem in tablets. It is mainly caused by the collision of the tablet's sieving machine or jinjian machine, but it may also be damaged by the punch. Lobes generally need to adjust the pressure of the press, speed, etc., generally can pass, if there is no need to pour, to see whether the funnel is blocked. For loose pieces, also want to adjust the pre - pressure, rotation of the main pressure, and then may be the cause of the particles, such as the particles are too dry, humidity is too small, viscidi
